Benefits of technology

The invention is a helmet / hood assembly with an open construction that results in significant weight and cost savings. The assembly includes a housing, a support ring subassembly, a face shield, and a hood. The face shield is flexible and attached to the housing, while the hood is fastened to the housing and extends outward from the head. The assembly also has an electrically driven fan powered by a battery. The technical effects include a lighter and more affordable helmet / hood assembly with improved ventilation and a flexible face shield that can be easily attached to the assembly.

Problems solved by technology

Turning the adjustment knob in a first direction causes the headband to tighten while turning the knob in the opposite direction causes the headband to loosen.

Abstract

A helmet / hood assembly includes a housing, a support ring subassembly configured to hold the assembly on a human head, a face shield, and a flexible hood attached to the housing and to the face shield, with the assembly being received, stored, used, and disposed as a single unit. The support ring subassembly pivots on the housing between a position suitable for shipping and storing the assembly and a position in which the assembly is worn. An accessory light powered by a battery may be held in place on the housing by magnetic attraction through the hood.

Description

RELATED APPLICATIONS[0001]Not ApplicableFEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTION[0003]1. Field of the Invention[0004]This invention relates to a helmet / hood assembly to be worn by surgical personnel and, more particularly, to such a helmet / hood assembly having a structure and assembly process configured to provide for a significantly reduction in the space required for storing the helmet / hood assembly.[0005]2. Summary of the Background Information[0006]For thousands of years, people have made and worn various types of helmets to provide protection of the head from physical injury in war, sports, various occupations, and in forms of transportation, such as riding a bicycle or motorcycle, in which the head is exposed.
